Among the most common HIV-associated lymphomas are Burkitt lymphoma (BL) and diffuse large B-cell lymphoma (DLBCL) with immunoblastic-plasmacytoid differentiation (also involving the central nervous system). Lymphomas occurring specifically in HIV-positive patients include primary effusion lymphoma (PEL) and its solid variants, plasmablastic lymphoma of the(More)
OBJECTIVE To characterize the therapeutic variables correlated to outcome in 370 patients with primary CNS lymphoma. METHODS Planned treatment was radiotherapy (RT) in 98 patients, chemotherapy (CHT) in 32, RT followed by CHT in 36, and CHT followed by RT in 197 patients. High-dose methotrexate (HD-MTX; 1 to 8 g/m2) was used in 169 patients and(More)
BACKGROUND The gene encoding the DNA repair enzyme O(6)-methylguanine DNA methyltransferase (MGMT) is transcriptionally silenced by promoter hypermethylation in several human cancers, including diffuse large B-cell lymphoma (B-DLCL). MGMT promoter hypermethylation is a favorable prognostic marker in patients with brain tumors treated with alkylating agents.(More)

The mitogen-activated protein kinase (MAPK) (also called extracellular signal-regulated kinase [ERK]) pathway has been implicated in malignant transformation and in the regulation of cellular growth and proliferation of several tumor types, but its expression and function in Hodgkin disease (HD) are unknown. We report here that the active phosphorylated(More)
AIDS-related primary effusion lymphoma (PEL) is an HIV-associated malignancy characterized by the ability of the tumor cells to specifically home in the serous body cavities. Here we used gene expression profile analysis (about 12 000 genes) to further define the phenotype of PEL and to investigate the lymphoma relationship to normal B cells and to other(More)
PURPOSE We characterized the candidacy of the six candidate genes mapping in the chromosome 15q25 locus, which was previously reported as associated with lung cancer risk, and confirmed the locus association with lung cancer risk in an Italian population of lung adenocarcinoma patients and controls. EXPERIMENTAL DESIGN We did a quantitative analysis of(More)
PURPOSE We have previously shown the presence of an activated platelet-derived growth factor (PDGF) receptor (PDGFR) B and its ligand PDGFB in a limited number of patients with clinical and radiological responses to imatinib mesylate treatment. This article describes the results of comprehensive molecular/biochemical analyses of the three receptors targeted(More)
